163

This number came up as a prime factor of 3749 in something I was doing. I saw where a mathematician called it, 163, his most fascinating number. Something about it being the first number in some arcane series of expanded primes and the last number in another one. Way over my head on the math, no mathematician here. Anybody know what he is referring to and can put it in non-mathematical terms?

Re: 163

Thanks. Did he mean every integer can be factored by primes?

Which it isn't.

Although 0 is an integer.

Re: 163

1 ought be a prime number. It would reduce the number of conjectures, which, I think we can all agree, would be nice

Re: 163

Edit: alternatively, it would increase the length of some conjectures and make them sound sillier, which would also be nice

It would make a lot of theorems far more annoying to state (or false).

Re: 163

So, basically, no downside at all

Re: 163

Is there a proof 1 is not a prime number?, based on the axiom/definition of a prime? I don’t think so. It is just stated so*, that way there is less to get tripped up on for the whole number system.

*see Plato if you have any doubts. Plus you can’t have the house of cards known as the integers collapse into chaos.

Re: 163

It is against the law to divide by the integer 0. So saith The Lord!

It's a deeply important* semantic debate about the meaning of the word 'and' in the usual definition.

Re: 163

Theorem
1 is an even number

proof:
1 is divisible by 1 and 1
1 and 1 is 2

therefore
1 is divisible by 2

Thus 1 is an even number

Re: 163

That is odd

Hence 1 is both even and odd
